PUMPING MECHANISM.

SPECIFZGATION forming part of Letters Patent No. 593,178, dated November 2, 1897. Application filed September 15, 1396 Serial No. 605,939, (No model.)

To all whmn it may concern:

Be it known that we, JOSEPH 1V. LEHR and HENRY F. MOORE, citizens of the United States of America, residing at Fremont, in

5 the county of Sandusky and State of Ohio,

have invented certain new and useful Improvements in Pumping Mechanism, of which the following is a specification, reference behad therein to the accompanying draw- [0 mgs.

The objectof this invention is to produce an apparatus for operating one or aplurality of oil-well pumps from a common point, and to provide a steady and uniform source of power for driving them, and to that end we employ mechanism whereby the rotary 1no-- tion of an ordinary engine or drive shaft is converted into a reciprocating action.

A further object of the invention is to provide, in conjunction with this mechanism, two pitmen, through which power is conveyed from the engine-driven shafts to the reciprocating plate; furthermore, in providing, in combination with the ball joints of the pitmen, intermediate joints having lateral mo tion to allow the pitmen to be adjusted when in horizontal positions.

A further object of the invention is to produce a device of the above-referred-to class 0 which will possess advantages in points of simplicity, efiiciency, and inexpensive construction.

W'ith the above and other objects in view the invention consists in the novel details of g 5 construction and in the arrangement as well as the combination of parts to be hereinafter more fully set forth, and specifically pointed out in the claims.

In describing the invention in detail refer- 0 once is had to the accompanying drawings, forming part of this specification, wherein like numerals denote corresponding parts in the several views, in which Figure 1 is a plan view of our improvement without connection with the engine or driving rods. Fig. 2 is a side view in elevation, and Fig.3 is a section view showing the construction of the base and turning plate.

In the drawings, 1 is the base-frame or foundation, which may be of any ordinary construction.

2 is the engine-shaft, from which motion is transmitted to the shaft 3 through the gearwheels 4, 5, 6, and 7.

Arranged at each end of the shaft 3 and secured thereto are arms 8 and 9, arranged at diametrically opposite angles with relation to said shaft.

At one end of the frame and secured thereto we provide a plate 10, which is provided with bearings 11, in which are journaled the rolls 1:2,designed to support the reciprocating plate 13, said plate having radial ways to receive the radially-extending arms 14, to which the pumpoperating rods (not shown) are attached.

Two arms 15 radiate from the plate 13 in opposite directions and when in their normal position are at right angles to the frame, and

at the ends of these arms are sockets which receive the balls 17 of the pitmen, by which aconnection is effected. Blocks 18 are mounted on the cranks, and to these the opposite ends of the pitmen are pivoted in a manner to permit of a lateral movement as the top of thetable rotates from the position illustrated, such arrangementpermitting the pit men to sustain equal strain at all points of the revolution. The halls are held in the sockets by an apertured plate 19. The pitmen may be adjusted by the screw-threads 20, arranged on the end carrying the ball.

In operation power is communicated through the gearing to the shaft 3, carrying the arms 8 and 9, and they in turn operate the blocks and pitmen. As the table oscillates the sides will alternately pass the line on which they stand, as illustrated. In passin g that center the pitmen will swing in the pivots of the blocks and adjust themselves to the swing of the table, the ball-and-socket, connection of the table allowing free movement at those points.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In combination, a plate pivoted at its center, radial arms extending from the plate in opposite directions, right-angular extensions on the end of the arms having hemispherical sockets in their ends arranged Vertically, pitmen having balls at one end op sockets, means for adjusting the length of the pitmen and pivotal pins for supporting the pitmen and allowing a transverse swing, substantially as described.

In testimony whereof We affix our signatures in presence of two Witnesses.
